Population and Sample in Statistics

Population — A population is the entire group that you want to draw conclusions about

Sample — A sample is the specific group that you will collect data from. The size of the sample is always less than the total size of the population.

Example for Population and Sample

Best Example for Population and Sample: Census(population) and Survey (sample)

Census: Gathering data from the whole population of interest.

For example: Elections, 10 Years Census, etc.

Survey: Gathering data from the sample in order to make conclusion about the population.

For Example: Opinion Polls, Quality Control Checks in Manufacturing Units, etc.
